Question

find volume and total surfcae area of cuboid height is 3/8 cm, length is 1 2/5 cm and width is 5/8​

Answer 1

Answer:

for volume=l×b×h and total surface area=2lb+2lh+2hw

first fraction converted into decimal point.3/8=0.375,12/5=0.4167,5/8=0.625.volume of cuboid=l×b×h=0.375×0.4167×0.625=0.97664 cm3. total surface area of cuboid=2lb+2lh+2hw=2×0.375+2×0.4167+2×0.625=2.8334 cm3
